"JSON Viewer":{ }

Paste JSON or open a .json file and explore it as an interactive, collapsible tree. Search keys and values, copy any node's path, or switch to a syntax-coloured formatted view. Runs 100% in your browser: zero network requests, so your data never leaves the page.

What is a JSON viewer?

A JSON viewer turns a wall of text into a structure you can actually read. Paste JSON or open a .json file and it renders as a collapsible tree: expand only the branches you care about, search for a key or value, and copy the exact path to any node. It is the fastest way to inspect an API response, a config file, or a large export without hand-counting brackets. Everything runs in your browser, so even files with tokens or personal data never leave your machine.

Tree view vs. formatted view

  • Tree: collapsible nodes with type-coloured values, search, and copy-path. Best for exploring structure and finding a specific value.
  • Formatted: classic pretty-printed, syntax-highlighted JSON with a line-number gutter. Best for reading top to bottom or copying clean output.

How to use

  1. Paste JSON into the Input pane, or click Open JSON file to load a .json file from your computer.
  2. The Tree view opens automatically: expand and collapse nodes to explore the structure.
  3. Use the search box to filter keys and values; click any node's path to copy its JSONPath.
  4. Switch to Formatted for a syntax-coloured, pretty-printed view you can copy.
  5. Messy JSON (single quotes, trailing commas, comments) is auto-repaired so it still opens.

Examples

Nested API response as a tree

Input
{"id":42,"owner":{"email":"[email protected]","roles":["admin","editor"]}}
Output
$
├─ id: 42
└─ owner: {2}
   ├─ email: "[email protected]"
   └─ roles: [2]  admin, editor

Open a .json file and read it

Input
(click "Open JSON file" → select data.json)
Output
The file's contents render as a collapsible tree. Nothing is uploaded.

FAQ

How do I view a JSON file?

Click Open JSON file and pick a .json file, or paste its contents. It renders as an expandable tree instantly, entirely in your browser, and the file is never uploaded.

Is my JSON uploaded anywhere?

No. The viewer runs 100% in your browser. Open DevTools → Network and confirm: zero requests after the page loads.

Can it handle large or deeply nested JSON?

Yes. Collapse nodes to navigate big documents, and use search to jump to a key or value without scrolling.

Can I get the path to a value?

Click the path chip on any node to copy its JSONPath (e.g. $.owner.roles[0]) to your clipboard.

What if my JSON is invalid?

The viewer auto-repairs common issues (single quotes, trailing commas, comments). If it can't be parsed, it shows the exact line and column of the error.
